SILICON ALLEY'S BILLION-DOLLAR CLUB: Meet the most valuable startups in New York City

There's no shortage of innovative and impressive startups in New York's Silicon Alley.

But only a handful of those companies have billion-dollar valuations.

Pulled from our recently published Silicon Alley 100 list, these are the most valuable startups in New York City.

All the companies on this list are private tech companies based in New York City that have raised venture-capital funding. Our list is not inclusive of every billion-dollar New York City startup; we've only included those from our SA 100 list. We ranked their value based on available information from the Wall Street Journal's billion-dollar club listing.

7. FanDuel

Fantasy-sports website FanDuel had a huge year; the startup raised a massive $275 million series E round in July from investors like KKR, Comcast Ventures, Google Capital, NBC Sports Ventures, and Time Warner Investments. The new funding valued Fanduel at $1.3 billion and pushing it into a growing group of startups with $1 billion valuations known colloquially as the “unicorn club.”

FanDuel, which competes with DraftKings, made its first two acquisitions this summer too. In July, Fanduel acquired Scottish app-development company Kotikan, and in August it acquired sports-analytics platform numberFire.

FanDuel is for busy or casual fans. It lets users participate in one-day leagues, as opposed to having to commit to season-long leagues. The company says it pays out over $10 million in cash payouts weekly.

5. MongoDB

In July, database startup MongoDBhired Michael Gordon as its new CFO — a man who is well known in the New York tech world for his work on many IPOs, mergers, and acquisitions while at Merrill Lynch. Gordon's joining MongoDB could hint at a possible IPO for the company, which has been a $1 billion "unicorn" company since 2013.

MongoDB has raised more than $311 million in eight rounds of funding, according to Crunchbase, the latest of which was an $80 million series G round in January. Tens of thousands of companies use MongoDB to build high-performance systems, including more than a third of companies in the Fortune 100.

Oscar wants to transform the healthcare industry by creating a better user experience when it comes to health insurance. It launched publicly in 2013 and had more than 40,000 customers across New York and New Jersey as of April, with plans to launch in Texas and California.

The unicorn company, which employs more than 600 people between its New York, Arizona, and India offices, is eight years old and has changed the landscape for booking appointments, and evaluating your experiences, with doctors in your area.
